Why is Epack Durable falling/rising?

As of 04-Aug, Epack Durable Ltd's stock price is currently at 381.00, reflecting an increase of 0.6 (0.16%). The stock has shown a strong performance over the past week with a return of +10.16%, while it has outperformed the benchmark Sensex, which only gained +0.16%. However, despite this recent uptick, the stock has underperformed its sector by -1.87% today. The company has reported healthy long-term growth, with net sales increasing at an annual rate of 33.30%. Positive quarterly results indicate significant growth in profit before tax and net sales, contributing to the stock's ability to generate a remarkable 50.21% return over the past year, despite a broader market decline.
In the broader market context, while Epack Durable has performed well in the short term, it is essential to note that institutional investor participation has decreased, with a -2.19% reduction in their stake over the previous quarter. This decline may indicate a lack of confidence among more sophisticated investors, which could impact future stock performance. Additionally, while the stock has shown resilience, it has a low return on capital employed (ROCE) of 8.32%, suggesting inefficiencies in management and profitability. The stock's valuation appears expensive relative to its earnings growth, as indicated by a PEG ratio of 1.1, which may raise concerns among potential investors.
